S32 SDK
FTM Combined PWM

Example application showing the FTM's combined PWM functionality

Application description


The purpose of this demo application is to show you the usage of the Combined PWM mode of the FlexTimer module found on the S32K144 using S32 SDK API.

Prerequisites


The run the example you will need to have the following items:

  • 1 S32K144 board
  • 1 Power Adapter 12V (if the board cannot be powered from the USB port)
  • 1 Personal Computer
  • 1 Jlink Lite Debugger (optional, users can use Open SDA)

Boards supported


The following boards are supported by this application:

  • S32K144EVB-Q100
  • S32K144-MB

Hardware Wiring


The following connections must be done to for this example application to work:

PIN FUNCTION S32K144EVB-Q100 S32K144-MB
FTM0 Channel 0 (PTD15) RGB_RED - wired on the board J12.18 - J11.31
FTM0 Channel 1 (PTD16) RGB_GREEN - wired on the board J12.17 - J11.32

How to run


1. Importing the project into the workspace

After opening S32 Design Studio, go to File -> New S32DS Project From... and select ftm_combined_pwm_s32k144. Then click on Finish.
The project should now be copied into you current workspace.

2. Generating the Processor Expert configuration

First go to Project Explorer View in S32 DS and select the current project(ftm_combined_pwm_s32k144). Then go to Project and click on Generate Processor Expert Code
Wait for the code generation to be completed before continuing to the next step.

3. Building the project

Select the configuration to be built FLASH (Debug_FLASH) or RAM (Debug_RAM) by left clicking on the downward arrow corresponding to the build button(. Wait for the build action to be completed before continuing to the next step.

4. Running the project

Go to Run and select Debug Configurations. There will be four debug configurations for this project:

Configuration Name Description
ftm_combined_pwm_s32k144 Debug_RAM Jlink Debug the RAM configuration using Segger Jlink debuggers
ftm_combined_pwm_s32k144 Debug_FLASH Jlink Debug the FLASH configuration using Segger Jlink debuggers
ftm_combined_pwm_s32k144 Debug_RAM PEMicro Debug the RAM configuration using PEMicro debuggers
ftm_combined_pwm_s32k144 Debug_FLASH PEMicro Debug the FLASH configuration using PEMicro debuggers


Select the desired debug configuration and click on Launch. Now the perspective will change to the Debug Perspective.
Use the controls to control the program flow.
